Abstract

A liquid crystal display device includes a liquid crystal display panel. The liquid crystal display panel includes a first transparent substrate having color filters arranged in a predetermined order, a patterned light blocking film formed between the color filters and first transparent electrodes formed on the color filters; a second transparent substrate having second transparent electrodes arranged to intersect the first transparent electrodes; a liquid crystal layer sandwiched between the first and second transparent substrates with the first and second transparent electrodes opposing to each other and spacers dispersed between the first and second transparent substrates. The color filters and the light blocking film extend into a marginal area outside an area optically switchable upon application of an electric field on the liquid crystal display panel in substantially the same geometric pattern as within the optically switchable area. A plurality of dummy electrodes can also be formed in the marginal area on at least one of the first and second substrates, so as to oppose the transparent electrodes on the opposite substrate. The extension of the color filters and the light blocking film into a marginal area and the disposition of the dummy electrodes in the marginal area can be applied in one liquid crystal display panel, singly or in combination.
